I actually can't think of anything more than one so I'm putting it here.
Yes, Glen Miller the jazz/swing musician whose plane disappeared. He is Christmas to my family.
Why? Do I hear you cry? Well, it all begins with a simple mistake at a record pressing plant/factory/whatever they call those places.
My dad was a subscriber to Readers' Digest and used to get all those adverts for records (and I'm talking vinyl here). Evrey now and then he would buy them and he bought one called "Christmas Through The Ages" - it's something like six records of Christmas music which is actually pretty decent stuff.
Record one, side two, doesn't have any carols or Christmas hymns, or even Slade. Oh no, instead it has Glen Miller.
So Glen Miller music always makes me think of family Christmases. All because of a mistake by Readers' Digest. Gosh, someone should write a book about that....
